Acts 17:31For He has set a day when He will judge the world with justice by the Man He has appointed. He has given proof of this to all men by raising Him from the dead."

1 Samuel 2:10Those who oppose the LORD will be shattered. He will thunder from heaven against them. The LORD will judge the ends of the earth and will give power to His king. He will exalt the horn of His anointed."

Verse 9. - For he cometh to judge the earth. Nature, inanimate and animate, may well be asked to rejoice when God comes to judge the earth - since he is sure to judge it aright. With righteousness shall he judge the world, and the people with equity. "God by his righteous judgment will bring the whole earth from a state of sorrow into a state of salvation and joy" (Hengstenberg).

98:4-9 Let all the children of men rejoice in the setting up the kingdom of Christ, for all may benefit by it. The different orders of rational creatures in the universe, seem to be described in figurative language in the reign of the great Messiah. The kingdom of Christ will be a blessing to the whole creation. We expect his second coming to begin his glorious reign. Then shall heaven and earth rejoice, and the joy of the redeemed shall be full. But sin and its dreadful effects will not be utterly done away, till the Lord come to judge the world in righteousness. Seeing then that we look for such things, let us give diligence that we may be found of him in peace, without spot, and blameless.
